clinical study to evaluate the safety and effectiveness of the treatment with tixel c on acne scars

Conditions: Scars

Summary: the purpose of this research is to evaluate the safety and effectiveness of the tixel c device for the treatment of acne scars, for improvement in the appearance of surface texture.

44 participents between two research locations with moderate acne scars will receive 3-5 treatments sessions with the tixel c device according to investigator's review of subject response. improvement of acne scarring will ve evaluated at 1 month, 3 months and 6 months post treatment. post-treatment response will be evaluated as well as any incidence of side efects throughout the study.
